Nature's ingenuity gives the crystal ornamental stone a rich variety of inclusions, unpredictable artistic shapes, and rich artistic conception.
What is the value of crystal stone:
1. Naturalness is the basic characteristic of crystal ornamental stone. Generally, the overall shape of crystal minerals does not have a high ornamental value, but the inclusion of crystal ornamental stones often needs to be polished and polished, which makes it easier to view the inclusions inside the crystal.
2. Odd characteristics Crystal ornamental stones are often very strange in terms of shape, texture and internal features. Nature has unlimited scenery, and you can find miniatures in the inclusions.
3. Rare natural crystals are non-renewable resources. With the deepening of development, the natural crystal stocks have become less and less. For sustainable development, the Donghai County government has long established a policy of protecting local resources and encouraging the development of overseas crystal resources. However, overseas resources are becoming less and less. Many countries have raised the threshold for mining and exporting natural crystals. The prices of foreign crystals entering the East China Sea market have skyrocketed year after year, and the viewing crystals have risen faster than ordinary crystals.
4, the chemical composition of the durable crystal is mainly silica, the chemical stability of the crystal is quite good; the hardness of the crystal is very large, and its Mohs (Moss) hardness is 7. These determine that the crystal will not rot and deteriorate, it is durable and easy to store, which is very suitable for collection.
